- This Grundig TK 23 tape recorder was purchased in Germany and there is concern about the supply voltage and frequency and whether the recorder will work here in Canada (120V, 60Hz) and play at the right speed so that tapes recorded in Germany can be listened to here.
My sister got such a Grundig back in '65 and I have used it time and time again to record the top charts tunes. Worked flawlessly. Very robust and HEAVY, a true tank. Nice to see those images over 50 years later !
When Dad bought it in 65, it came with 2 motor wheels, one for 50, and the other is for the 60 cycle, the wheel had some sort of a metal fan... We changed them when we moved to a 60 cycle country. I still have 2 models of these recorders:-):-)
If you need parts and/or any help just ask, as i have restored many R2R grundig machines including the big TK46/47/54/64/8/16/820 and the little series TK 20/24/25/28. But sorry they are not very High Quality besides the old tube TK47/820.
As when you got more than 110V most of the times you better select 130V or you may blow the machine when using continued for hours....
Go inside and re-select the unit for your mains voltage. You can search as well for the 60hz conversation motor kit.
"Netz" = is for on/off. "klang" = Tone control
To lift the top cover you´ll need to lift the head cover (the triangle platsic in the middle) first, as there are screws underneath on some machines (as i´m not as familiar with the TK23)
The head cover comes off very easy, just pull it gently with your fingers maybe with a shlight sidewhise pushing.
Machine does operate without tape. But you´ll need to get into it and do some re-lubrication and check the belts as well, as the rubber on all the wheels.
Cool, what you´re hearing past 20:55 is some "schäbisch", some vernacular spoken words located in south-west of germany, a region where the "mercedes-benz" cars are made;)
Push the red button to record, but it does only operate when you´re have stopped the machine.
Thanx for posting anyway!
Thanks for the advice and information. I believe there's a simple wiring change with the motor leads to change from 50Hz to 60Hz. Are you familiar with that wiring change?
There should be one, i think you got the "23L" model, i have some service manuals for old grundig R2R i need to check for your model. If it´s in there i inform you by tomorrow, as i need to dig into my papers, as it was prior to computers;)
(Max) Grundig did some odd things to his machines to keep the cost down. You´ll find out when you open it.....But i like especially the all tube models TK28/46.
TubiCal Just checked the two folders around here, but it´s not inside. I still got some more in the attic, i´ll go checkin´ them by weekend....
TubiCal Thanks for the help. I have access to the full manual in German. On the schematic, it clearly shows how the motor terminals need to be wired. My problem is I don't know how the four motor terminals are numbered. If I knew that, I'd be home free. I should study the manual more. Gute Idee.
TubiCal Please don't go to more effort - I now know what I need to know from Dennie Lee's comment. Jim.
THE RED BUTTON IS THE RECORD.YOU HOLD IT DOWN THEN PRESS PLAY TO RECORD.THE MIC BUTTON I THINK SWITCHES FROM LINE IN TO MICROPHONE
I noticed around the 9:20 section near the voltage selection jumpers there were two sets of wire terminals; the wires were connected to the 50 terminals on the outside and there were also unconnected 60 terminals inside those... Probably a method of selecting the correct line frequency!
Fantastic Dennie!! I didn't see those numbers myself and the terminal arrangement exactly matches the schematic. It's clear that the unit is still wired for 50 Hz. Thanks! Jim.
A means Automatic level recording. T means Trick, you can record on old recording without erasing. Sound on sound.
I had an Uher with bad motor run capacitors, the motor was weak and hot to the touch.
They all too often need new BELTS. Clean all that dry grease and oil. I hope the rubber is OK.
What's the button on the side of the piano key control? An interlock for record? Did you experiment with the red control? Try it in stop mode. Perhaps it's a pause too, so as to set record levels. Um thinkin it may be one speed.
The head cover comes off with the top, all one piece.
Well, I have GRUNDIG TK-17, which is pretty similar to this, but just older model with rounded-edge case, not square ones as this one. I bought it while leaving in the US and then had sent it back to Russia in 2007. In the US I had speed problem with it, since it was also designed to use 50Hz power, so speed appeared to be 20% faster then usual 9.5 cm/s. Of couse, in Russia I just relocated these fuses to 220V power position, resoldered power cord to the transformer to the correct 220V position, and speed appeared to be correct, true 9.5 cm/s. And as for speed, I believe there were some service shops in the U.S. earlier, who offered replacement of the roller wheel from 50 c/s to 60 c/s version, since in my GRUNDIG I see the wheel inside saying 50 c/s on it, so definitely 60 c/s wheels for it also existed. My GRUNDIG still works fine!
awesome very interesting ....
It did sound a little fast but to find a kit today for 60hz would be a pain in the rump. Most of the kits had a shaft part you would glue onto the 50hz shaft to make it 60 hz.
If using it for voice and not prerecord audio tapes would be ok. But any tapes that are prerecord will play wrong. Also it looks mono so stereo tapes would not work good on it anyway.
There's a wiring change to accomodate 60Hz. Looks like someone changed the voltage setting but didn't change the frequency connections - you need a soldering iron to do that.
I believe the red button is for record the reason why it's got the a and the T there and it's spring loaded is because the a probably represents listen and the t represents transcribe our record. The thing is, is that the machine is German made and they do and label things differently. So the spring loaded button just represents the fact that unless you turn it towards t and press down on it you won't be able to record or accidentally erase your tape. So what you probably have to do is turn it towards T and either press down on it or if you turn it towards T and then press play it may engage that red button and lock it in the T or transcribe position and you will be able to record. And yes they did use odd labeling to represent the functions, it can get a bit cryptic. You kind of just have to figure it out.
amberola1b I did not want to engage the record function while I was investigating the button for fear of putting a blank spot on the tape. I'm sure you are right about how it works.
This machine, although it seems solidly built and heavy enough, suffered from a host of small, yet incredibly infuriating design mistakes that would lead to tape disasters with chilling regularity. I owned this machine from 1993 to around 2005; inherited it from my late grandpa (in a broken state) along with a bunch of ancient cellulose tapes with prerecorded popular 1960s music. Ask me about the countless hours I spent repairing this antichrist while it was connected to the mains and full of spinny metal parts - in order to help me troubleshoot mechanical problems - and how many hours I spent rewinding incredibly fragile tapes by hand which have pooled onto a massive jumble on the floor because the takeup wheel mechanism on the antichrist had failed once again and I didn't notice the disaster until it was way too late. Having rediscovered all of the taped 1960s songs which I enjoyed on the internet, I gutted the damn thing for parts and tossed the carcass. I don't miss it.
Hello ! Do you know how to connect output the machine to a soundcart ? It a din wire, I think but where from, please ? Thanks !
You have the very rare Grundig reels! Nice machine. Did you get it all nice and fixed? Thanks for sharing.
+I967 It's not mine but it sure looked cool. I can't remember how that one ended but I believe it needed a different speed wheel. I could be thinking of another machine though.
I think one control a volume and the other tone or one volume and one record level
at 9:20 there are a blue and green wire soldered to #50 Terminals - 2 #60 Terminals are open.
Seems to be a single Speed Maschine with original 50Hz recording thus playing too fast.
Netz = grid - Netzschalter = power switch
Klang = tone control
Lautstärke = playback volume
Mic - seems microphone. Maybe a selector switch line or mic?
Anything else?
Ausst. Would be record level.
That red thingie is for sure the record switch mostly to operate together with Start.
No idea for A and T. Automatic rec level adjust? But T?
Have had aTK42 for many years myself. They all are mainstream not Hi End.
Hi Bernd. Thanks for spotting the 50Hz / 60Hz terminals.
Jim,
What exact type is it? Grundig built -U versions (eg TK23-U) which were 50/60Hz selectable.
For other types like -L vor without any addendum one could buy conversion kits. Probably some shaft sleeve / driver pulley.
For Detail See the Herman radio Museum www.radiomuseum.org/r/grundig_tk23.html
Regards,
Bernd
Oops, shitty auto correction. German Museum of course.
I bought a Grundig 23l de lux in Paisley in Scotland in 1965 it cost 52 pounds and 10 shillings I lost it latter when i was traveling I still have a lot of tapes from the sixtys and would like to buy a working tape recorder to play the tapes
Taky , jsem jeden dál do kupy ,ale má to dost těžkou mechaniku
Sir this is stereo or mono
How many watts
Pls answer me pls
Oh please let me show him ?
GRUND -- DIG !!!!!!!!!!
Do you sell your tape recorders after you fix them. I would like to buy a Grundig 23 l delux
rosaleen mclaughlun Sorry Rosaleen I don't sell anything. But I know of a good shop in Toronto. You can email me if you would like to know more. jlindenas@gmail.com
Nice reel 2 reel. I have exactly the same. Replaced some caps and now working great.

Von einem Ami habe ich auch nichts anderes erwartet. Dafür null Ahnung.
He's in Canada and he can Google Translate this, you know. :)
You are not the brightest pencil in the box, are you?
